Answer
Sales tax Payable = $780
Entry to record transaction is:
Dr: Cash $16,380
Cr: Sales Tax Payale $ 780
Cr: Sales $ 15,600
Explanation:
Coghlan Auto Supply sales are inclusive of tax so at first step it is necessary to segregate sales tax from the total sales of $16,380.
In order to calculate sales tax in Coghlan total sale divide the total sales figure with 1+the sales tax rate i.e (1+5%=1.05)
So the sales exclusive of  tax will be:  $ 16,380/1.05 =  $15,600
Tax can be calculated now by subtracting Net sales by gross sales i.e $16,380-$15,600 = $780.
